Would you agree with me on Metallica prog rock?

Here's the thing, Metallica never tried to sound like emerson lake  and palmer ever. That is except for one song that they did.

(maybe I'm crazy, and this band didn't sound like elp, or maybe I'm onto something)

And that'd be one song from their album, kill 'em all. 

Basically my question is, do you agree that metallica only made one song where they imitated elp?

And if you've heard the song tank, by elp, you might agree.
